Looks great. What I'd like to know is how you're keeping all the cards cool enough. I have 2 5970s that sat that close together and the 1 card hit 101c while benching. I even briefly considered wc. Ended up going core i7 to get space in between the cards where I'll have a fan blowing air between them. I'll be assembling this rig shortly and would appreciate the heads up.

My case has a 140 mm fan blowing cool air into the cards intake fans, it seems to do the job, then again the 5970's are hotter running cards. my GPU's idle at 37C at under load never get above 78C

I never noticed the fan 'til I shifted the pic. Sounds like that's the way to go. Thanks

Edit:Heck, I'll be happy to pay for something if the ladies deliver it,hehe. Seriously, that was downright awesome of XFX to donate those cards. Yeah, I couldn't get sound from my HDMI. What did they do?. Sent me a cable to connect the card to the board, just like that. Kudos to XFX!!!
